A long wire A carries a current of 10 amp. Another long wire B, Which is parallel to A and separated by 0.1m from A, carries a current of 5 amp, in the opposite direction to that in A. what is the magnitude and nature of the force experienced per unit length of B 
A
Repulsive force of 
B
Attractive force of 
C
Repulsive force of 
D
Attractive force of 
Text Solution
